The V6 is a class 'C' only car in the Cockshoot.

Race fees and dates are very similar for both.

There are more ZS's in the cockshoot, basically all the ZS guys bar Peter Burchill run in the Cockshoot.

Cockshoot Class C can run slicks and full race wets, you could run road tyres also.
Peter Best is road tyres only.

The new gen road tyres are fast, not much slower than a slick.
New Gen wets, such as rainsport 3 are fast in the wet.
Whilst there are gains in full race tyres, they are not huge amounts faster like yesteryear or like some trackday heroes think they are.

Brand new race tyres are more money than road tyres, but you can pick up used slicks for very little money and race wets, whilst rare are not much used.

I looked seriously at the Peter Best for 2017, only to be told by hierarchy that there will be such little interest and attendees in class C that its not worth bothering with!!!

The ZS struggles in parity against the ZR190 at most circuits (this is not a held belief in the Peter Best, but TSL timing evidence supports what I say) but at least you will be racing against other ZS's in the cockshoot.

Would be a bit unfair to expect the ZS's to be faster than the ZR190's tho wouldn't it they are to be fair running a full race engine
